Is “because” a coordinating conjunction?
No, “because” is not a coordinating conjunction. Instead, it is classified as a subordinating conjunction when used in sentences like this: “I bought this phone because it has a good battery.”
The inclusion of “because” in the clause “because it has a good battery” makes it a dependent clause. This clause cannot stand alone as a complete sentence and relies on the independent clause “I bought this phone” to complete its meaning.
